The application of X-section beams in the modular and strength-based design of a precision planter chassis was investigated numerically and experimentally in a case study. This study deals with the feasibility of a special section design with a systematic engineering approach. Mechanical tests were performed for the beam evaluated in a mounting system. The X-section beam model and the mounting elements on this beam were created using computer-aided engineering software, and the compatibility of the design with the mass criterion was investigated. This model was edited as a 2D and 3D mixed model and analyzed with the finite element method to analyzing studies of the system. Stress measurement was conducted using strain gauges at specified points in the system whose prototype was produced. These strain data were processed with nCode DesignLife software, and nonlinear FEA analyses were validated using these stress measurements. The fatigue damage of the X-section beam under dynamic loading conditions was investigated using the FE model solution and experimental measurement data (CAE-based fatigue analysis) with nCode software. The X-section beam design adopted a multiple-objective genetic algorithm technique for optimization by means of ANSYS. The maximum stress value was 121.83 MPa, and a 7.77 kg material was saved correlated to the prototype with the help of optimization solved 400 iterations. It has been determined that the X-section beam is safe by 1.06 × 106 cycles under these loading conditions and can carry a load of 1600 kg. The X-section beam can be successfully applied in similar systems owing to its assemblability and functionality.

Thin-walled hollow shapes are of great interest in many industries with weight constraints, due to their availability, low price, and strength-to-weight ratio. This paper presents the development, calculation, and production of a thin-walled X-section beam design with a unique section geometry. This hollow X-section beam geometry is a beam that has been developed to use shape-connected jaws on the beam and to use less bolts and mounting elements, and to easily change the positions of the parts mounted on the beam. The bending strength of this unique beam section was investigated, and the fatigue damage of the beam was also handled with technological methods. Using both experimental stress measurements and finite element solution, the static and fatigue strength of the beam were calculated with computer-aided engineering software. The FEM solution was performed nonlinearly by defining the linear elastic and plasticity properties of the material. Validation studies were carried out in the laboratory using three-point and four-point bending tests. These traditional experiments were supported by strain gauge technology that measures strain with 0.05% accuracy. The weight and bending strength of the X-section beam were compared with the hollow section square beam. X-section beam (S355J0H) has 13% lower bending strength than 120 × 120 × 8 mm (S355J0H) beam; however, it is 37% lighter. ANSYS-analytical test results of difference are 3.95%, and ANSYS-experimental test results of difference are 0.85%. Experiments showed that a ∼22% increase in strength is found in these corners depending on the production method. The fatigue behavior of the X-section beam was determined with the nCode DesignLife software using validated FEM solutions and fatigue curves of the materials. X-section beam developed for shape–connected assembly systems can be used especially in the formation of chassis with its superior assembly ability and bending strength, increasing functionality, and production speed.

In this paper, the effects of the shield gas on cut quality in plasma arc cutting were quantified experimentally. Measurements were performed on plasma arc cutting kerfs (PACs) cut through a 4 mm (1/8 in.) S355 steel plates with a Gys Neocut105 cutter equipped with a Toparc AT-125 torch. This system uses compressed air as both cutting and shield gas. Separate circuits for shielding air and cutting air were used. This way, the influences of the shield air and the cutting air could be studied independently. A full 3-factor, 3-level Taguchi design was followed. The studied factors are the cutting air pressure, the shield air pressure, and the arc current. The measured responses are the removed steel surface and the right and left bevel angles. As expected, the current proved to have the greatest influence on the kerf surface. The cutting air pressure significantly influenced the kerfs’ shapes while the shield air flow rate proved less important yet sensitive. Some negative bevel angles at high plasma, high cutting, and high shield air pressures have also been observed.
